The techniques of not doing are those that have no other point of view than tranquillity, although this is not its objective either. The objective is simply to be centered. They are extremely difficult techniques, suitable for people with practice. Not to think about anything, not even, not to think, is an act that requires a certain mental balance. A Zen way of expressing Do Not is this. I don't think, No, I don't think.

Although one of the goals of meditation is to experience what happens when one is mentally calm and concentrated, and with the body relaxed, most techniques are aimed at making that happen when the mind is prepared, rather than actively pursuing it.

It is essential to remember that the mind must be calm, without thinking about it, without realizing anything it hears, without perceiving its body. It is the direct and immediate experience of nothing, to rest in nothingness, as the silent moon rests in space, then the moon disappears, leaving nothing to rest in nothingness. But it doesn't end here. When a person experiences a complete outer silence, he has the impression of opening up to a completely new realm of being. Instead of experiencing nothing, it seems to experience everything, an undifferentiated whole, which is not separated, without one thing distinguishable from the other. Instead of emptiness, one has infinite fullness.

Throughout the centuries, mystics have tried to describe this experience through art, poetry and literature, but it is indescribable. There are those who consider this experience as a sign of divine favor, and at the opposite extreme, some consider it an aberration of the brain. Although in the history of humanity it has been interpreted in all ways and in the light of different religions and theories, as experience alone is. In fact, trying to induce it can be a way of blocking it, although some zazen techniques use the frustration of trying to create a state in which the mind finally bursts into silence, becoming open and serene.
